Be it known tha l, Josemi F. Lerrone, a citizen of the 'United filiales,residing at Miles Ciy, in ehe county of Custer end Siate ofIlfloiilarm,y have invented certain new and'ueeful improvements inCombined Road Grader@ and Rollers; and l do hereby declerc theAfollowing to be er lull, clear. and

exact description ofthe invention, such as' will enable othersvskilleclin the art to which ie/appertains lo make and use the same.

My invention relates to that type of machine generally designated asroad graders, and'lxas for its object to simplify and improve theconstruction iheieoi, anni also to provide features which adapt themachine for use as a roller.

The numeral 8 indicates a long :incl still scraper blade which iscarried by the rucli and is adjueiably supported thereby, throughconnections, preferably/ arranged as follows: l The numeral 9infilo-aies a pair of forwardly converging thrust bars, the liront endsof which are connected to lie back of 'the'scraper blade 8, inwardiromthe endo lhereolE, by ball arial eoclretA connections l0, best shown inFigo. The reali enti porM tions of these thrust bars l) are'attaeliecllo chains are passed around ami adapted to be moved bypairiplierally notched sheaves lf2 alici lllv secured to a 'veriicalshalt l5 journalefl in suiable bearings on the transverse yoke 16 of themain frame l. it its upper end, the said shaft lo may be provicled witha. hand.

To the cehlral porzioii o' chie boem 18 isrigidly secured a cellier bearing plaie l@ lo 'which iepivoally'cozmected lower nearing plaie 20.

The saifl beam lll is caueecl to par talco of rhehorizontal angular movemeiif; of the scraper blade 8. by' means. ofToile 22 oivoally connecte@ thereto arid to the l'iruei bars 9. Ylhescraper blade iefheld against emlwise movements l-raoevereely of vthemo,- chinei by means of oblique brace rods or bars 23, shown as@iwf-ally connected lo the iront ends ci elle lhrusi; bars 9 and toprojecting lugs 20* on the pivotally movable j' e 20.

The pivotal connections between the brace rods 23 and lugs 20a' are veryloose, so that there Will be no binding action when the rods 23 changetheir angle ,in respect to a horizontal plane. To set the scraper bladeat any desired pitch or scraping angle in respect to the ground, theupper edge thereof is connected .to the front ends of the thrust bars9,'l'iy means of longitudinally adjustable bars 24". These bars 24 areshown as made up of sections mounted to slide, one upon the other andhaving perforations 25 through any one of Whicha pin 26 is adapted to beinserted to maintain the longitudinal adjustment ofthe said bars.

Swivel blocks 27 are pivotally connected to the endsof the oscillatorybeam 18, and vertically extended screw-threaded adjusting rods 28 areswiveled in the'lsaid blocks 27, being held against vertical movementsby collars 2 9 on the said rod. At its upper end, these rods 28 areshownr as provided with end wheels 30, bymeans of which they may berotated and their threaded lower ends work in internally threaded'sleeves 31, the lower ends of which are loosely pivoted to the frontends of the thrust bars 9.

The operation of the machine, briefly del scribed, is substantially asfollows: By oscillations of the shaft 15 and the sheaves 13 and 14thereon, the chains 11 and 12 may be manipulated so as. tosimultaneously force one of the thrust bars 9 ahead and the other thrustbar 9 rearward. 1n this Way. the scraper blade maybe set to Work eitherat a right angle in respect to the direction of travel of the machine orat any angle in respect to the direction oi' travel, lrcceding rearwardtoward either side oi' the machine. The comiccting rods 22. as alreadystated, cause the beam 1S to partaice ot' the horizontal angularmovenifnts oi the said scraper blade, so that the adJr.iingr rods 2Rwill always be held in vertical positions. By rotation of bothadjustingr rods in the same direction, both ends of the scraper blademay be raised or lowered and set either in an elevated inoperativeposition. or to scrape to any desired extent the surface of the groundtraveled by the inuchine. lly uneven, or different n'iovcnients of thesaid adjusting rods 18 the one end oie-the scraper bladel may be raisedmore than the other and thc scraper blade vthus sci'. to round over orbevel the sides ot' the road or to do other work requiring the scraperblade higher at one end than at the other. Obviously, tne rorxning ofembankments or trenches will require one end of the scraper blade to beadjusted much higher than the other. It willthus be seen that all of theadjustments required. in a finishing road grader or scraper are providedfor by an extremely simple and ellicient mechanism capable of easymanipulation. In fact, the entire machine is of comparatively small-costand generally eiiicient for the purposes had in View.

What I claim is:

1. In a grader, the combination with a truck, of a scraper blade, anoscillatory member carried by the said truck, oblique rods pivotallyconnected at their inner ends to said oscillatory member on oppositesides of its axis, and connected at their outer ends scraper bladeagainst cndwise movements transversely of ,the machine, and meansholding said scraper blade in different horizontal angulanadjustments. Y

2. In a grader, the combination with a truck, of a'scraper blade, Vanoscillatory member carried by the said truck, oblique rods pivotallyconnected at their inner ends to said oscillatory member on oppositesides ofrits axis, and connected at their .outer ends to said sera crblade, thereby holding said scraper blafe against endwise movementstransversely of the machine, and means holding said scraper blade indifferent horizontal angular adjustments, a device for verticallyadjusting said scraper blade, and

or angular adjustments thereto.

8. Tn a grader, the combination with a truck and a beam mounted ou theframework" thereof' for horizontal `oscillatory moveu'ienis, of ascraper blade below said. beam, thrust bars connected to said scraperblade on opposite sides of its center, a pir oted member connected tothe central portion of said oscillatory beam. oblique rods oonnecttal attheir inner'cnds to said pirotcd member and connerted at their outerends to the front end portions o said thrust bars. verticallytuljustablil .screw connections between the ends ol said beam and saidscraper blade. rods connecting said thrust bars to said oscillatoryvvbeam.l and means for i simultaneously 'forcing one of said thrust barsforward and the other rearward.
